In the states we had a service bulletin covering the window rubbing the top. The solution was not in aligning the window but in changing out the springs which are located just behind the rear side-window weatherstrip inside the "c-pillar" (if you can call it that on a Cabrio with no "b" pillar), wrapped in a plastic "hose" type sheath and tie-wrapped in place. Replacing these is easy and results in greater top tension which keeps the top from sagging and hitting the window.

The gas spring is quite expensive from BMW in the states, like over $85, each. The last set I got came from Eurasian in CA, USA and cost closer to $25. Replacing one usually works ok but at $25 each, I'd do both. The cheaper unit was packaged by SWAG of Germany, their part no. 7.06.1250. BMW oe. part # Both units are labeled Stabilus Gas-a-Just, Koblenz, WG. only one carries the BMW emblem. Replacement is simple. Remove the plastic cap on the top and remove circlip, remove circlip at bottom and slid it off. The new ones are only a bit harder to align as you hang upside down doing it. Leverage with a screwdriver on the bottom sometimes helps.

Good Luck
